| 摘 要： | 为了研究多天线系统的信道容量特性,从信息论角度对使用多个发射和接收天线的多输入多输出(MIMO)系统的信道容量进行了理论推导,通过建立MIMO系统模型,分析了频率选择性衰落信道下的MIMO系统信道容量,重点探讨了信道相关性、天线距离以及RicianK-因子等因素对MIMO系统容量的影响,运用信息论理论对其进行了量化的分析,并通过计算机仿真进一步验证了结论。

| Abstract: | In order to research the channel capacity of multiple-antenna systems,multiple input multiple output(MIMO) channel capacity formula is studied based on the information theory.By building the model of MIMO system,the paper analyzes the channel capacity of MIMO system under frequency-selectivity fading channel.Our analysis and discussion are focused on the effects of antennas,the channel correlation,and Rician K-factor which influence the MIMO capacity.The results proposed are validated by computer emulator. |
